SYLVESTER GARNER, OF OOVINGTON, VIRGINIA, ASSIGNOR TO OOVINGTON MACHINECOMPANY, A CORPORATION 01 VIRGINIA.

COKE-EXTRACTING MACHINE.

Specification of Letters Patent.

Patented Jan. 7, 1908.

To all whom it may concern:

Be it known that SYLvnsTER GARNER, a citizen of the United States ofAmerica, and resident of Oovington, Alleghany county, State of Virginia,has invented new and useful Improvements in Coke-Extracting Machines, ofwhich the following is a specification.

My invention relates to improvements in machinery for the extraction ofcoke from ovens and more particularly to that class of machinery inwhich a plate or shovel is forced through the door of the oven and underthe coke, and the coke is then withdrawn, either by pushing it out ofthe door on the opposite side of the oven, or else by drawing it out ofthe door through which the tool or shovel is inserted, by the withdrawalof the latter.

The invention relates particularly to that class of machinery in whichthe tool which removes the coke from the oven is carried upon a carriagemoving on a track in front of a series of ovens, which carriage iscausedby appropriate mechanism to travel in front of the row of ovensand to insert and withdraw the tool into and from each oven and so moveit when in the oven, horizontally and vertically, that all parts of theoven in succession will be subjected to its effect.

In this particular class of coke extractor the plate or shovel isattached to a bar or ram, whichbar or ram slides in an appropriatecarriages, between rollers and is necessarily of such length that theshovel or plate attached to it may reach the most remote parts of thecoke ovens.

The object of the present invention is to provide a shovel which willdraw out more and larger pieces of coke from the furnace at every strokethan has heretofore been possible. I accomplish this by making the flatportion of the shovel which is attached to the bar or ram in the form ofa circle or a semicircle or a cycloidal curve, and providing it with asharp edge in the manner hereinafter described, the opening within theshovel being of such size that the coke will readily fall through thesame and into any receptacle provided.

The invention will be best understood by reference to the accompanyingtwo sheets of drawings, in which Figure 1 is a vertical and end view,partly in cross-section, of a coke extractin machine of the type shownin United States Letters Patent issued to \Villiain II. McConnell,768,067 on the 22d day of August, 1904, to which the present inventionis applied. Fig. 2 is a plan view of the carriage of the McConnellmachine, showing the retracting bar and the shovel thereto attached.

Similar letters refer to similar parts throughout the several views.

In the drawings, E represents the bed plate of the machine, which ismade rectangular in form and is of the same general type of bed plate asshown in the aforesaid patent. This is mounted on the pedestals T, whichin turn are mounted on the axle V of the wheels IV.

S represents the rails upon which the extractor moves, placed in frontof a series of coke ovens upon the ties K.

B is the bar or ram of the coke removing tool, attached to which at oneend is the scoop or shovel A, forming the subject of the presentinvention. The ram B is mounted upon a horizontal rotating'ram carriageD as shown in Fig. 1 in the patent above referred to, and is arranged toslide therein between a series of vertical rollers O, O, which rotate inappropriate boxes inserted on the top of the bottom plate H of thecarriage D as shown in Fig. 1. The ram B is supported by threehorizontal rollers I, I, I, one of which is supported in the extensionpiece at the forward end of the carria e. The ram B is held down onthese rollers by the roller It on the forward. end, and by a similarroller at the rear end. A variety of devices may be used for controllingthe movement of and to move the ram, but these play no part in thepresent invention. The ram is provided with the toothed rack c, whichengages with the spur wheel Q connected with appropriate mechanism fordriv ing the same forward and backward, and the whole carriage turnsupon the rollers M, on the top of the bed plate E. The shovel iscomposed preferably of two pieces a and a the former being a straightcrosswise head or back and the latter being a curved auxiliary head. Inthe drawing it is shown substantially semi-circular, but as stated aboveit may be of any convenient shape. The lower surfaces of the parts a anda are made flat, as shown in Fig. 1, and the part a is beveled astshown,so as to make a sharp edge which can pass under the coke.

G is a'receptacle placed between the carriage and the furnace, intowhich the coke as it falls from the shovel is discharged. This may be atraveling conveyer which is the form shown, or a table or otherconvenient device. The cross head may be cut down to the same height asthe ring-shaped head, making a plain ring of the same. In the drawing itis shown made slightly higher for the purposes of increasing the amountof coke which is drawn at each stroke, and beveled on its inner face. Italso may be given a curved direction if desired. If desired the shovelmay be made in the form of a solid ring, with a flat lower surface, andbeveled outer face attached to the end of the bar B.

The method of operation is as follows: The carriage is rolled in frontof the coke oven, the operating mechanism is brought into engagement andthe ram B forces the shovel into the coke oven, under the coke and liftsit and separates it. The turning mechanism will then throw it to eitherside so as to disengage the coke. Part of the coke falls behind, andwhen the shovel is retracted it is thrown out by the outer face of thecross head, as well as by the inner face of the auxiliary head a. Onsliding back from the edge plate of the furnace when the shovel emergesfrom the furnace the coke falls through the ring-shaped opening, uponthe oonveyer or other carrying device, and is carried ofl. The operationis then repeated, turning the shovel at any convenient angle withrespect to the axis of the furnace, and retracting the same andcontinuing the operation, until the coke is all removed.

The use of the form of shovel hereinafter I described and hereinafterclaimed is not of necessity limited to use in connection with thecarriage for manipulating the same automatically, but the same may beused by hand, in which case the ram B will be replaced by a suitablehandle at the end, for enabling the operator to manipulate the shovelsubstantially in the same manner as the same is manipulated by theautomatic mechanism.
